4/27/2026, 4:17:15 AM
Casualties and Targeted Sites
Strikes in Ukraine, Russian-occupied territories and Russia killed at least 16 people. Russian drone and missile attacks on Dnipro left nine dead, regional governor Oleksandr Hanzha reported. A Ukrainian drone hit Sevastopol in Crimea, killing one civilian; a Ukrainian strike on a village in the Russian-backed Luhansk region killed three; a Ukrainian drone also killed a woman in Russia’s Belgorod border region. Ukrainian forces struck the Yaroslavl oil refinery inside Russia, igniting fires at the facility.
Damage to Chernobyl’s New Safe Confinement
Ukrainian officials claim a Russian drone hit the outer shell of the New Safe Confinement (NSC), the $2.1 billion arch completed in 2019 over Reactor No. 4, in February 2025. The IAEA says the strike compromised a key safety function of the enclosure, raising risk to the original sarcophagus that contains the melted core. The European Bank for Reconstruction and Development estimates repairs will cost at least €500 million. Ukraine’s energy minister Denys Smyhal reported partner pledges now total €100 million, on top of a previously agreed €30 million.
Official Statements & Responses
President Volodymyr Zelenskyy warned that Russian attacks could trigger a new nuclear disaster on the Chernobyl anniversary. IAEA Director General Rafael Grossi called for immediate repairs to the New Safe Confinement’s outer shell. Energy Minister Denys Smyhal said partner commitments total €100 million, on top of a previously agreed €30 million. Russian Defense Minister Andrei Belousov, in North Korea, said Russia and North Korea had agreed to transition military cooperation to a sustainable, long-term basis.
Criticism & Opposition
The IAEA has labeled the drone impact on the New Safe Confinement “nuclear terrorism,” condemning it as a breach of safety norms and warning that inaction could heighten danger to the original sarcophagus.
Conflicting Reports & Gaps
Ukrainian officials assert a Russian drone struck the NSC in February 2025; Moscow denies the attack and alleges Kyiv staged it. Independent verification of the strike and casualty figures in Dnipro, Sevastopol, Luhansk and Belgorod remains unavailable.
